sPEcIFIcATIoN forming part ofLLetters Patent No. 278,366,, dated May 29, 1883,

Application filed February 21, 1883. (No model.)

To all whom inner concern 1 Be it known that I, HANS H. SATER, of Dubuque,in the county of Dubuque and State of Iowa, have invented a new and useful 1m clare that the followingis a full, clear, and exact description of the same.

My invention relates to an improvement in cultivators; and it consists, first, in a novel coupling to connect the drag-bar tothe frame of the cultivator, in order to permit the shovels to have both a vertical and lateral movement; second, in the peculiar manner of atin the novel manner of attaching theshovels erally; and, fifth,ir1 the draft attachment.

In the general construction my cultivator consists of apair of carrying-wheels mounted which is mounted the drivers seat, anda pair of levers, by which the elevationof the dragframe,is accomplished. V y The invention is illustrated in the accomtion of the draft attachment; Fig. 4, a section through the drag-bar, showing the attachment of the shovel-arms; Fig. 5, details of the parts theparts composing the coupling; Fig. 7, a detail of one of the shovels and its attachment to its supporting-arm; and Fig. 8, a sepa- In these drawings, A A are the carrying- Wheels, of ordinary construction. B is the main portion of the axle, which is a horizontal wooden beam, having depending arms at its end, preferably of metal,-and formed with cylindrical horizontal journals upon their .ends for the wheels. Upon this axle is mounted the frame 0, having at its rear end the drivers seat]), and extending forward to a pointwhere it is connected to the ordinary tongue.

F F, with which engage suitable devices caroted upon opposite sides of the frame-work, thedonger arms extending backward, so as to be accessible to the driver. The short arms of the levers are connected by chains H H to the drag-bars I I. Secured to the frame-work, in front of the axle, is a cross-bar, J, and from this cross-bar are suspended arms 1 1 2 2, each pair of such arms forming a portion of' one of the coupling devices, and, as such couplings are similar in all respects, only one of them will be described in detail. Referring more particularly to Fig. 2, each of the'arms 1 1 is bent at right angles a short distance below the cross-bar, up to which point the arms are in contact and secured together by bolts 3 3. 6 The arms are again bent at right angles, so that a fork is formed, between'which is held the couplings. Upon the lower inner end of each of the plates 50 51, secured to the armsof the fork, is a conical or frusto-conical pro- 7:

'je'ction, 4,,and a perforation extends through these plates and arms and such projections. 3 5 represents a hollow sleeve, provided on one face with corrugationsti, andhaving its end formed into conical bearings to fit the projections 4 4. A bolt, 7, passes through the parts when in position, having nuts upon its end fit ting within a square countersink on the outside of the arms 1 1, as shown, by which means the sleeve can be tightened on its bearings shouldit wear loose. This sleeve is held in engagement with a vertical sleeve, 9, having at each end conical bearings 10, similar to those upon the horizontal sleeve, and upon one face horizontal corrugations 11, which engage 8 with those of the horizontal sleevejust described. The ends of the forked standard 12 .work freely upon the bearings 10, and are held in position bya bolt pa ssin g through the same, and nuts upon the end. The parts are all held 0 in engagement by a link,13, and set-screw 14, similar to that described in myapplication for patent filed in the United States Patent Office on the 8th day of J anuary, 1883.

It is evident from this description that the 5 drag-bars can be elevated through the levers and chains described, the horizontal sleeve working in its bearings on the arms 1 1, and

at the same time a lateral movement may be given such drag-bars,the arms of the forked mo standard working on the-vertical bearings of the other sleeve.

The second part of my invention relates to the peculiar manner of attaching the shovelarms to the drag-bar, in ogderto permit such arms to yield on meeting an obstruction. To the outside of the drag-bar, and near its end, is rigidly secured a plate, 16, havinga central perforated boss or standard, 17, upon the outer end of which is an arm, 18, extending at right angles to it and parallel to the drag-bar. Upon the end of this arm 18 is a pivot, 19. Aplate, 20, of the shape shown in Figs. 4, is mounted upon such pivot, and is provided with a long curved slot, 2], and with a triangular shoulden, 22. The shovel-arm 23, at its upper end, is recessed to fit this shoulder, and when the parts are in position the shovel-arm is held between the plate and the arm 18, while a bolt,

24, passes through the drag-bar, the boss 17,

the vshovel-arm,.and the slot 21 in the outer plate, 20. It will now be evident that while the shovel-arm is rigidly secured to the plate '20 such plate can turn upon the pivot, and will slide up and down, by means of its slot, upon the bolt 24, so that the entire arm and the shovel attached to it will yield upon meeting an obstruction of sufficient rigidity, and can be readily put back by the operator without leaving his seat.

I have devised an' improved means of connecting the shovel to its arm, which is shown in Fig. 7. To the rear of shovel 26 is bolted a block, 27, the upper end of which is slotted to permit the point of the shovel to be moved laterally, and secured in any position within its range of movement. An eyebolt, 28, is connected to the said block,which isclamped rigidly in place by the nut 29 and the jam-nut 30. It is evident that the shovel may be readily raised and lowered upon the arm by simply loosening the jam-nut,which will allow the shovel and block to be adjusted as desired.

Fig. 8 represents an improved device for adjusting the drag-bars. To the rear side of the axle is secured a rigid rod, 31, and upon this rod is mounted a sleeve, 32. This sleeve is connected tothe drag-bars by arms 3334, the upper ends of which are bent into circular form, so as to surround the. sleeve and be braced upon it by bolts, as shown. Between the upper end of the arms and the main portion thereof, which are almost in contact, is held a notched beam, 35, through which the bolts 36 pass. It is evident, then, that by loosening such bolts the arms can be moved laterally and compressed upon the sleeve at any point, the operation effecting the spreading of the drag-bars to any desired extent.

The last portion of .my invention relates to an improved draft-attaching device, and is shown in Fig. 3. Upon the front of the axle is pivoted a curved arm or equalizing-bar, 37, to the ends of which are attached chains 38,which pass over drums or rollers 39, secured to the metallic or depending portion of the axle. These chains are connected by the slotted draw-bars 40 to the single-trees 41, and may be adjusted at this point of connection as variations inthe draft may require. The drawbars pass through a metal loop, 42, secured to v the cross-bar J of the frame previously described, such loop being provided' with a number of holes, by which the height of the single-tree can be adjusted. The ends of the equalizing-bar 37 are also perforated, in order that theend of the chain may be'placednearer to or farther from the center, according to the amount of leverage which each horse properly requires. The bolt 45, preferably having a roller device, passes through two of the perforations of the loop, and upon this roller the slotted draw-bar plays. Brace-rods 46'conuect the arms which hold the coupling to the loops and to other portions of the frame, in order to give greater solidity and firmness.

Having thus described my invention, what I claim isizing-bar, the perforated loops 42, the slotted draw-bars, the chains and drums, and the single-tree's.

2. The combination, with the arms 1 l and the plates 50 51, having the integral cone-bearings, of the horizontal and vertical sleeves connected to the drag-bars.

3. The combination of the drag-bar, the plate 16, the perforated boss, the plate 18, the plate 20, pivoted thereon and having the slot 21, and the shovel-arm rigidly secured to the said plate.

In testimony whereofI have signed my name tothis specification in the presence of two subscribing witnesses.

I I HANS H. SATER.
